viiage 4; Whicliis provided Withtwo pairs of rollers 5 Vvad'aptedto rest upon and move along horizontally Vdisposed beam members j 6. Iliesefbeain members which may advanta geously-be` of I-sec'tion lare disposedon loppo- `^sta ll s, one of which is shownin Figure 1, is 80 i site sides of the center line of the track upon which the locomotive'is adapted to be moved lthe roundhouse.v weight of the duct 15 will not be transmitted within the stall and while they may be supported in any convenient manner, they have been illustrated as resting upon the structural members 7 connected to any adjacent portion of the roundhouse.

In each form of the invention the carriage comprises two pairs` of longitudinally extending frame members S and 9, respectively, which are preferably connected adjacent *their endsby transversely extending frame members 10. The rollers 'are positioned between the longitudinal frame membersy of each pair and are mounted upon shafts 11 which may be advantageously journaled in the latter. To provide convenient means for `moving the carriage a sheave 12 is keyed to one of the shafts 'l1 and this sheave is provided with a flexible device such as an cndless chain 13 so that it may be readily rotated by an operator from the floor of the round house. It will, of course, be appreciated that one Aof the rollers 5 on the shaft upon which the shcave 12 is mounted must also be keyed to the shaft to effect movement of the carriageV by rotation of the sheave. As may be clearly seen 1n Figure 3 the sheave 12 is 'spaced a suliicient distance from the carriage so4 that its operating chain will hang to one 4side of the associated locomotive.

' In the form of the invention illustrated in Figures 1 to 4, inclusive, the duct which is connected to the carriageis designated by the reference numeral 14. At its upper end this duct is pivotally connected to a duct 15 which leads into and has communication with a duct 16 in'nnovably mounted in the roof of In order that the entire to tlie duct 14 the former is preferably countferbalance'd by a weight 17 attached thereto provide a relatively snug lit between the two,

the upper portion of the former is spherically shaped, as at 20, and is adapted to be disposed within the lower portion of the latter which is Ipreferably enlarged as at 21. The means for pivotally connecting the ducts may ad# vantageously be a bolt 22 which passes through the center of the spherically shaped `portion of the duct 14. The lower portion of the duct 15 is cylindrically shaped and its internal diameter is just slightly greater than the external diameter of the spherical portion of` the duct- 14. In this manner it will be :seen that the angular relationship between the two ducts may be greatly varied and yet the connection between the two is such that exhaust gases from the locomotive will be prevented from escaping` into the roundhouse.V

Secured to the lower end of the duct 14 is a plate member 23 having an aperture for receiving a vertically movable duct 24 adapted to telescope within the duct 14. In order to conveniently connect the plate member 23 and the duct 14 the latter is provided with a marginal flange 25 for receiving screws 26 or the like which pass through the plate. The lower end of the duct 24 is fashioned with a horizontally disposed laterally pro jecting flange 27 adapted to rest upon the stack of a locomotive.

As it is sometimes necessary to move the locomotive while it is in operative association with the exhaust apparatus, means is preferably provided whereby movement of the locomotive will induce movement of the apparatus. In the present embodiment of the invention this means comprises two pairs of members 28 and 29, respectively, which depend downwardly below the liange 27 on the duct 24. The members 28 are mounted wit-hin the duct 24 at the inner edge of the flange 27 and are adapted to extend into the stack of the locomotive while the members 29 are mounted adjacent the outer edge of the flange 27 and are adapted to be disposed on the outside of the cooperating stack. By providing two pairs of these members it will be appreciated' that the amount the stack may moverbefore coming into contact with one of them is very much less than the amount the locomotive could move, relatively to the duet, should only one pair be employed. The

outer pair of the depending members are pivotally connected to the duct 24 by pins or the like 30 and by frangible pins 31 so that should the locomotive be moved beyond the limits of horizontal travel of the carriage, the force transmitted from the stack of the locomotive to the cooperating member of the outer pair will shear the frangible pin of that member, thus permitting the latter to assume an inoperative position and enable continued movement of the locomotive without damage to the exhaust apparatus. The inner pair of the depending members is also connectedto the duct by frangible pins but since both members are disposed in the path of movement of the stack when the locomotive is moved in either direction each of them is connected by two of such pins 32 and 33. It will thus be appreciated that when the stack of the locomotive moves to the right vas viewed in Figure 4 pin 32 of the left one of the inner members will be sheared while pin 33 ofthe right one will be sheared whereby the members are enabled to respectively rotate about the unsheared pins.

To obtain a tight lit between ducts 14 and 24 and yet permit relative vertical movement betweenthem a packingdevice is pref the plat-e 23 adjacentthe -aperture formed' .,thereinfforthe reception .of-theduct 24.

While any suitable means maybe employed Y forlmoving the :telesco'ping duct 24Il'prefer to` employ mechanism; which may rbe. easily y h 4 Instead yofj connecting the "fan directly'to* .the motor shaft it is preferred lto connectV it and, quickly. manipulated from vthefloorof the roundhouset.l -Thusthe ymechanism'com- .prises a pair ofdrums 37 rigidly mounted on ashaft 38 which may be -jou'r'naled in a brackv `et-39.4 As maybeperceived this bracket is .of

.U-shape Aand the 1egsther`eof,in-which the shaft 38 ismounted,1are preferably secured to the; duct 314 by lbolts 40 andI to the carriage frameby rivet-s 41.?v Connectedto the drums 37 are yflexible means42, such aschains,fcables or the like which are respectively attached to `bars43 secured to the flange 27 of the duct. :24. These bars, whilethey afford convenient' means to'which the leX-ible' chains 42 vmay be attached, are vprimarily designed to guide the @duct 24 asit is being'moved; .For this reason the. bars` 43 passythrough .-aperturesin the marginal. flange 25 formed on the duct r14, the f flange being enlarged adjacent the apertures as at 44.*1 The guide bars also'pass through apertures formed in brackets 45 rigidly connected to the innerof the longitudinal frame l .mem-bers 8 andk 9 and tothe duct 14, these bracket members constituting the means for rigidly connecting the duct 14to ythe carriage.

v*Rigidlyl mounted `uponthe Vshaft 38 is a pinion 461which' meshes with .a worm `V47 kformed on la shaft'48 mountedrina bracket 49`which; is secured by any suitable means to the:l bracketv member 39'. Keyed to the shaft 48 is a'sheave 50-'equi'pped with an end- 4less chainI l51.1'whi'ch extendsy downwardly. so lthat it may be readily grasped'by. an oper'- atoron .the floor? ofi the roundh-ouse. l So that thelowerendof the chain will be spaced fromlthe sidegof thelocomotive it is .led over., 'a `pulley 52 carried by anrar'm 53 which extends downwardly and outwardly from the `bracket 39y and isA suitably braced by a mem- "ber 54 secured to the carriage 4; It will `thus be seenthat by'rtating the shaft 38 upon .which the drumsv 37v -are' lmounted through theintermediacy of the worm and pinion gear, the sheave 50 and the chain 51,

Vthe telescoping duct maybe moved vertically whereby it may. be brought into/operative association with locomotivesy having' stacksA of different heights. i -Forg inducing a Vdraft .within Vthe duct a f fan'55 yis disposed within the duct l4-which is operativelyconnected toa motor 56 a' shaft 57. In order that the axis of rotation" of-the fan will be" parallel` to .the axis-of that. portion ofthe duct immediately adia- 1 cent fit' the duct 14 isfprovided with an yelbow "455 orofset portion58.

draft within the ducts. Immediately below the upper bearing 70 the cylindrical portion 69 is provided with a `plurality of passager ways 72 whereby cool airlmay be drawn through the cylindrical portion into the duct to prevent overheating of this bearing. If desired thecylindrical portion may be rigid- 'ified or reinforced by a web 7 3'. i v

Since the diameter of the duct 14 illustrated in Figures 5to 7,'inclusive, is less than than that of the' corresponding duct illustrated in Figures 1 to 4, inclusive,the bottom plato 23 may be omitted in this form of the invention and the packing ring may be secured directly to the lower marf ginal flange 25 of the duct.

The means by which the carriage is moved horizontally and the means by which the telescoping duct 24 ismoved vertically are the same in this form of the invention as in the form illustrated in Figures 1 to 4, inclusive. 1

In the form of the invention illustrated in Figures 8 and 9 there .is provided an immovable duct 74 mounted in the roof ofthe roundhouse and a duct 75 which is pivoted at its upper end to the first-named duct. The duct 75 may be conveniently made in two sections which are weldedvor otherwise secured together as at 76. The upper end of thc upper section of the .duct 7 5 is offset the same as and formed similarly to the upper portion of the duct 14 illustrated in Figures 5 to 7, inclusive, the motor being mounted and associated with the duct 75 in the same manner as with the duct 14.V

The lower end of the duct 75 is provided with a flexible bellows 77 which may be of any suitable material. such as treated canvas, woven asbestos, light metal or the like. The bellows is `supported by and secured to an apertured plate or the like 78 provided with a plurality of `upwardly and outwardly extending arms 79 secured to the transverse frame members ot' the carriage 4. To protcct the Abellows from the hot gases 4which pass through the ducts from the locomotive a tubularshell 80 maybe advantageously provi-ded, the shell being connected to the plat-e 78. v i

To guide the lower end of the duct 75 blocks or vbracketsffl may be employed which are formed with inwardly projecting trunnions 82 which passthrough the duct. -The blocks are also fashioned with apertures through which'the guide bars 43 of the telescoping duct 24 pass, the guide bars being associated with the carriage in the same manner as in thereof.

4other forms of' the invention. It will thus be perceived thatfwhen the carriage 4 is moved horizontally causing the duct 75 to rotate about the point at which it is pivotally 001i-, nected to the immovable duct 74 the lower telescoping duct 24 vertically is the same as that disclosed in the other forms of the invention, instead of mounting this mechanism on a bracket or the like above the carriage it mounted directly on the latter at one end not,l however, connected to the upper ends of the guidev bars 43 but instead is connected to the duct 24 adjacent the lower ends of the guide bars, being led over sheaves or the like 83 mounted upon the frame'members of the carriage.

Fromtheforegoing it will be perceived that the invention which has been disclosed in several forms is so constructed that it may be easily and 'quickly' manipulated to bev brought into operative association with a locomotive'to conduct the exhaust gases there of to the exterior of the roundhouse. l
